Writing Skul's character

So as a part of writing my crossover fic I focus on Skul's character a lot. I'm trying to stay true to the original, but I'm willing to make some major changes from the series. I think there are many sides of him that would be interesting writing about.

So which sides of him you would have wanted to read about? (in general, not necessarily extensions of canon stuff, write whatever you want lol 🙃)
